Where is the energy actually going, and how much of it survives the drivetrain?
These are the measurements that decide the answer, and the ones most often taken badly.
Efficiency measured across an inverter whose switching noise swamps the reading.
Loss separated correctly between the inverter, the motor, and the cable.
Transients during a fast-charge handshake that last microseconds and matter for years.
Repeatability between two benches that are supposed to agree.
Where the measurements are taken
Instantaneous power and conversion efficiency
Inverter / drive
Efficiency is only real when input and output are measured at the same instant, on the same time base.
Transients and multi-channel waveforms
Motor
Start-up, regeneration and the fault that happens once all live in the same recording.
Internal resistance and open-circuit voltage
Battery / ESS
A cell degrades in its internal resistance long before it degrades in its voltage.
Temperature and humidity over long periods
Environment
An electrical drift with no recorded temperature beside it is a number without a cause.
Power and energy over time
Distribution busbar
Consumption is attributed by circuit or it is not attributed at all.
Instruments used in mobility
Bring us the mobility measurement you are stuck on.
Describe the installation and the quantity. We will say which instrument group measures it and what the measurement actually needs to resolve.
What has to be true inside the company
Four criteria of innovation, and the reason a measurement can be trusted outside it.
Increasing customer value
Production system
A production system built so that a measurement need turns into a delivered, calibrated instrument without the customer absorbing the delay.
Delivering peace of mind to customers
After-sales service
An instrument is only as good as the number it still reports in year five. After-sales service exists to keep that number trustworthy.
Pursuing productivity and precision
Manufacturing capabilities
Precision is a manufacturing capability before it is a specification. It is held in the process, not promised in the catalog.
Creating new customer value
Collaborative development of new products
When a field has no instrument for the quantity it needs to see, the instrument gets developed with the customer who needs it.
